American Express is expanding its Twitter Sync services by allowing users to pay-by-tweet. The social commerce model is especially beneficial to the company since each purchase is a small advert for American Express. Users who sync up their American Express cards can tweet to purchase a limited supply of discounted items and tweet to confirm each purchase within 15 minutes to complete the transaction.
American Express Twitter Sync was launched in March of 2012 for users who wanted to get discounts on qualifying purchases. Purchases had to be made in person, but now Amex customers can buy items with two tweets and have them delivered to their door.
Currently, you cannot purchase items as gifts as they only be delivered to your billing address and there’s no way to change this feature. It would not be feasible to tweet a recipient’s address in a public tweet for millions to view. Twitter’s security was compromised for 250,000 users earlier this month so it would be wise for Amex to proceed with caution.
